Hi,
I'm trying to write my own remote shell program,
It simply connects to a remote server then copy the sock fd to stdin,
stdout and stderr. And it works.
But I found several problems:
1. It doesn't handle characters like ^A ^E or tab (any bash/readline stuff)
-> openssh itself doesn't seem to incorporate readline, so the
magic is not on readline
2. If I run command like VIM, it doesn't run.
And buttons like "<ESC>:q" won't work
Can someone enlighten me about what SSH did, so it all works perfectly?
Attached the prototype:
int sockfd = socket(PF_INET, SOCK_STREAM, 0);
struct sockaddr_in remaddr = { 0 };
remaddr.sin_family = AF_INET;
remaddr.sin_port = htons(9999);
remaddr.sin_addr.s_addr = inet_addr("192.168.56.1");
if (connect(sockfd, (struct sockaddr *)&remaddr, sizeof(struct sockaddr)))
ERR_QUIT("connect");
for (int i = 0; i < 2; ++i )
dup2 (sockfd, i);
execl("/bin/bash", "/bin/bash", "-i", NULL);
